Resumo: The objective of this work was to evaluate the effect of six water depths on the reproduction factor and gall index of Meloidogyne incognita race 1 as well as yield of eight pea cultivars in Cerrado conditions of the Federal District, Brazil. Treatments were replicated four times in a completely randomized block design and combined eight pea cultivars (Triofin, Mikado, Marina, Viçosa, Maria, Luiza, Amélia and Kodama) besides six water depths, 479, 395, 311, 239, 177 and 156 mm. There was no interaction between cultivars and water depths for the nematode reproduction factor and gall index, but there was for yield. The means for reproductive factor and gall index per cultivar in the six water depths did not differ, showing that the cultivars presented the same degree of susceptibility. However, the general means of the eight cultivars for each water depth showed that the reproductive factor reduced by 60% in water depths of 156 and 177 mm, indicating that the nematode did not tolerate water deficit. Cultivar yield did not differ, considering water depths of 239 to 395 mm, but it reduced to 12, 30 and 40%, respectively, considering water depths of 479, 177 and 156 mm. Pea cultivars reached the best yield under water depths of 239 to 395 mm.

O delineamento experimental foi em blocos ao acaso com parcelas subdivididas e quatro repetições. Os tratamentos constaram da combinação de oito cultivares (Triofin, Mikado, Marina, Viçosa, Maria, Luiza, Amélia e Kodama) e seis lâminas de água (156, 177, 239, 311, 395 e 479 mm). Não houve interação entre cultivares e lâminas de água para fator de repodução e índice de galhas do nematóide, mas houve para produtividade de grãos. As médias de FR e IG por cultivar nas seis lâminas não diferiram entre si, mostrando que as cultivares apresentaram o mesmo grau de suscetibilidade ao nematóide. As médias das oito cultivares por lâmina de água mostraram redução do fator de reprodução em 60% sob lâminas de 156 e 177 mm, indicando que o nematóide não tolerou a condição de déficit hídrico do solo. As produtividades não diferiram nas lâminas de 239 a 395 mm, mas foram reduzidas em 12, 30 e 40%, respectivamente, sob lâminas de 479, 177 e 156 mm. As cultivares de ervilha alcançaram melhores produtividades sob lâminas de água entre 239 e 395 mm.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCharchar, João MariaMarouelli, Waldir AparecidoGiordano, Leonardo de BrittoAragão, Fernando Antônio Silva2005-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7055Pesquisa Agropecuaria Brasileira; v.40, n.10, out. 2005; 989-995Pesquisa Agropecuária Brasileira; v.40, n.10, out. 2005; 989-9951678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7055/4103info:eu-repo/semantics/openAccess2014-09-19T18:59:45Zoai:ojs.seer.sct.embrapa.br:article/7055Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-19T18:59:45Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
